MACHINE FOR INSERTING PEN POINTS AND INK FEEDS IN FOUNTAINQPEN BARRELS.

Application filed March 31, 1922. Serial No. 548,298.

This invention relates to improvements in a machine for mechanically inserting the ink feed and pen point into a fountain pen barrel.

Among the objects of the invention are to provide a machine for accurately positioning fountain pen feed and pen point simultaneously into a fountain pen barrel, whereby the same are successively placed in fountain pen barrels in identically the same manner and in a much shorter period of time than is commonly used in inserting the pen point and pen feed manually.

Fig. 1 is a side elevational view of the machine.

Fig. 2 is a plan view of the machine.

Fig. 3 is a right end elevation of the machine shown in Fig. 1.

Fig. 5 is a detail taken along the line 55 in Fig. 1. 1

Referring to the drawings, on the base 1 of the machine is supported a standard 2 on which is mounted a chuck 3. This chuck serves to hold the ink feed and pen point rigidly while it is being inserted in the pen barrel. The chuck comprises a hollow bearing 4 which is held in place by means of a set screw 5. On the outer periphery of this bearing is mounted a hand wheel 6 within the rim of which is internally machined an eccentric hole 7. In the hollow bearing 4 is a cam 8 held in place by set screws 9 on which the pen and pen feed rest. The plunger 10 is vertically positioned in the chuck and has a padded end 11 which contacts the bottom of the pen feed, the rounded upper head 12 of the plunger being acted upon by the internal eccentric or cam surface 7 of the hand wheel 6. A spring 13 is interposed between the head of the plunger and the bearing portion 4 to hold the plunger against the cam surface 7. When the pen point and ink feed shown at 14 and 15 respectively, have been inserted in the chuck, the hand wheel 6 is turned so that the internal eccentric or cam surface will lower the plunger to set against the ink feed and rigidly hold the same with the pen point, in position in the chuck. On the opposite end of the base are two bearing lugs 16 in which is mounted the pivot pin 17 On the pin 17 is also mounted the movable support 18 which carries the transverse shaft '19 upon which is mounted the hand wheel 20. On this shaft 19 are also mounted the gears 21 which mesh with the racks 22 machined in the bottom of the mandrels 23 and 24. In the top of the mandrels are key ways 25 which serve to restrict the travel of the mandrels due to the set screws 26. The mandrel 23 serves as a gauge, being the exact lengthof a'pen barrel and having the hole 27 in the end thereof bored to exactly position the feed and pen point in the chuck so that when a barrel is mounted upon the mandrel 24 the pen and penfeed will be properly positioned therein after being gauged in the mandrel 23. In operation the support member 18 is rotated upon its axis, the pin 17 so that the gauge mandrel is centered before the chuck. At this time the latch 28 will drop into the slot 29 and hold the support rigidly in position. The hand wheel 20 is then turned to feed the gauge mandrel toward the chuck and the pen and pen feed are then properly adjusted in the gauge mandrel so that they properly feed the hole 27 in the end of the mandrel. The chuck is then firmly set onto the pen and pen feed by rotation of the wheel 6 and the pen point and ink feed are rigidly held in the chuck ready to be inserted into the pen barrel. The hand wheel 20 is turned in the opposite direction and the gauge mandrel withdrawn from the ink feed and pen point. The latch 28 is then raised and the support rotated to a position where the mandrel 24 is centrally positioned before the chuck. A pen barrel such as that shown at 29 has been placed upon the mandrel and the mandrels are again moved forward by the hand wheel 20 so that the pen and ink feed held in the chuck will be accurately inserted in the end of the pen barrel. The forward movement of the mandrels is restricted by the set screws 26 extending into the key ways 25, thereby accurately limiting the extent to which the pen and ink feed are inserted in the pen barrel. In addition to being held by the latch 28, the support 18 has lugs 30 which contact with the stops 31 when the support is rotated to either of its two positions.

I claim as my invention:

1. In a fountain pen machine, the combination with a means for adjusting an ink feed and pen point for insertion in a pen barrel, of a barrel holding means adapted to be positioned before the ink feed and pen point, and means for advancing the barrel to insert said ink feed and pen point therein.

2. In a fountain pen machinefthetcomv bination With a gauge and barrel holding elements, of adjustable means for rigidly holding an ink feed and pen point, means for positioning the gauge element before the pen and ink feed to adjust the same to be fitted invthe .pen barrel, means for removing the gauge and advaneingvthe pen barrel for mechanically inserting the pen point and ink. feed therein.

3. In a fountain pen machine, the combination with an adjustable means for. holding the ink feed and pen point, of a gauge element for adjustably setting the pen point andinl; feed to be aceurately positioned in the pen barrel, of means for mechanically Withdrawing the gauge element and p0sitioning a pen barrel to receive the ink feed .and pen point.
